BENJAMIN PAUGH, OF PARSONS, WEST VIRGINIA.

M NDREL- Specification of Letters Patent.

Patented Oct. 16, 1906.

Application filed May 11, 1906. Serial No. 316,314.

T on whom it may concern:

Be it known that I, BENJAMIN PAUGH, a citizen of the United States,residing at Parsons, in the county of Tucker and State of West Virginia,have invented a new and useful Mandrel, of which the following is aspecification.

This invention has relation to mandrels especially adapted to be usedfor winding rolls of paper; and it consists in the novel constructionand arrangement of its parts as hereinafter shown and described.

The object of the invention is to providea mandrel with a web which isadapted to be laterally extended with relation to the exterior surfaceof the mandrel, so that when the paper is rolled upon the mandrel andthe said web is extended that the central opening of the roll of paperwill be of greater diameter than that of the mandrel proper.Consequently when the roll is completed the said web may be withdrawnwithin the mandrel, and the said roll of paper may be readily slippedfrom the end of the mandrel. Suitable mechanism is provided for theextending or withdrawing of the web with relation to the exteriorsurface of the mandrel.

In the accompanying drawings, Figure 1 is a top plan view of themandrel. Fig. 2 is a longitudinal sectional view of the mandrel, andFig. 3 is a horizontal sectional view of a portion of the web and itsimmediate operatmg connections.

Mandrel 1 is hollow and is provided at one end with a suitable handhold2. The gearwheel 3 is located upon the said mandrel, or any othersuitable means of rotating the same may be provided. The. collar 4 isalso located upon the exterior surface of the mandrel, and the surface 5is located between the collar 4 and the gear-wheel 3 and affords abearing-surface for any suitable pattern of bearing. (Not shown in thedrawings.) The mandrel 1 is provided with a longitudinallyextending slotor opening 6. The outer edge of the web 7 is located in said openingwhen the said web is withdrawn and passes through the said opening whenthe said web is projected with relation to the outer surface of themandrel. The pins 8 8 extend transversely across the diameter of themandrel 1, and the web 7 is provided with the inclined perforations 9,which receive the said pins 8. One end of the web 7 is provided with thevertically or transverse extending elongated perforation 10. The shank11 is located within the mandrel 1 and is provided with atransverse-extending pin 12, which passes through the perforation 10 ofthe said web 7. The said shank 11 is adapted to move longitudinally, butis held against rotation. The said web 7 is adapted to movelongitudinally and laterally simultaneously, but is held againstrotation with relation to the mandrel 1 by means of the edges of theslot 6. The end of'the shaft 13 is swiveled to the end of the shank 11.Any suitable joint, such as 14, may be employed for this purpose. Theshaft 18 is also housed within the mandrel 1. The shaft 13 is providedwith a laterally-extending pin 15, which passes through thespirally-inclined slot 16, located on the side of the mandrel 1.

The operation When it is desired to project the edge of the web 7 withrelation to the exterior surface of the mandrel 1, the pin is movedthrough the length of the slot 16. tion of the said slot moves the shaft13 longitudinally and simultaneously rotary with relation to themandrel 1. The shank 1.1 is slid longitudinally within the mandrel 1.The web 7 moves longitudinally and simultaneously laterally withrelation to the mandrel, and thus its outer edge is projected throughthe slot 6. The movement of the web 7, above indicated, is accomplishedby means of thednclination of the perforations 9, receiving the fixedtransversely-extending pins 8. The laterally-extending perforation 10,receiving pin 12 of the shank 11 permits of the lateral movement of theweb 7 with relation to the said shank. In order to withdraw the edge ofthe web 7 within the slot 6 of the mandrel 1, the operation abovedescribed is reversed.

of the device is as follows:'
